African American DNA Research Forum

My brother tested and we are from the Balkan Islands, Europeans also. My g grandfather's dad was a white slave owner who migrated to NC My g grandfather was stated as Mulatto in the 1870 Census, by 1900 his race had changed to Black.. His mother possibly from Africa. We have not found out who his mother was yet. We have have found that he had at least one brother who was Black. There maybe more siblings that I have not found yet. Thanks.
